During glomerular filtration, what pressure is supporting or increasing GFR?
|
|
blood hydrostatic pressure
|
|
|
colloid osmotic
|
|
|
capsular pressure
|
|
|
None of the above

Explanation:
Detailed explanation-1: -The forces that govern filtration in the glomerular capillaries are the same as any capillary bed. Capillary hydrostatic pressure (Pc) and Bowman’s space oncotic pressure (i) favor filtration into the tubule, and Bowman’s space hydrostatic pressure (Pi) and capillary-oncotic pressure (c) oppose filtration.
Detailed explanation-2: -The glomerular capillary hydrostatic pressure is affected by the afferent and efferent arteriolar resistance and the renal artery pressure (3). An increase in the afferent arteriolar diameter (decrease in resistance) causes an increase in the glomerular capillary hydrostatic pressure and an increase in GFR.
